ANCHORAGE- The threat level of an Alaska volcano has been raised following an ash emission Tuesday.
   
The Alaska Volcano Observatory raised the advisory level for Pavlof Volcano to orange from yellow following the 11 a.m. emission.
   
Geophysicist Dave Schneider says seismicity accompanied the emission, which was continuing and first noticed by a pilot.
   
Satellite images show ash move southeast of the 8,262-foot volcano, which is located about 625 miles southwest of Anchorage. Pilots have reported the cloud at about 19,000 feet.
   
Pavlof began emitting ash last month, but activity calmed, leading officials to downgrade its threat level on May 28.
